Mickael Maison commented on KAFKA-14206:
----------------------------------------
The 3.4 branch has been upgrade to use ZooKeeper 3.6.4
(https://github.com/apache/kafka/commit/704830488066f1905d529d583ed0212432986048).
The upgrade to 3.7 will not happen in the 3.4 branch so I removed 3.4.1 as the
fix version for this.
> Upgrade zookeeper to 3.7.1 to address security vulnerabilities
